S3 M7 Cellular Regulation Flashcards
Hematopoieses
Rapid continuous turnover of blood cells
Leukemia
Hematopoietic malignancy of the a particular blood cell
can be granulocyte, lymphocyte, erythrocyte or megakaryocyte
Leukemia defects originate in
hematopoietic stem cells
the myeloid
lymphoid stem cells
myeloid
nonlymphoid blood cells
RBCs, platelets, mast cells, macrophages, WBCs
Types of leukocytes
eosinophils
basophils
monocytes
go out of whack with leukemia
Acute myeloid leukemia AML 101
occurs before 45y
Most common nonlymphocytic leukemia
Death chances increase with age
Death is usually from infection of bleeding
Manifestations of AML
Acute myeloid leukemia
Neutropenia - fever and infection
Anemia - fatigue dyspnea pallor
Thrombocytopenia - petechia, ecchymoses, bleeding tendencies
AML and manifestations inorgans
Pain in liver or spleen from enlargement
Bone pain from marrow expansion
Hyperplasia (enlargement) of gums
Hyperplasia of synovial space of joints
Diagnostics of AML
CBC - v in erythrocytes and platelets
v in Leukocytes
Bone marrow analysis - 20% increase in immature leukocytes aka Blast Cells Hallmark of diagnosis
AML treatment
Aggressive chemo - induction therapy (hospitalization for weeks)
results in low ANC
Packed RBCs and Platelets for ANC
G-CSF or GM-CSF - promote granulocyte and macrophage growth
Treatment for APL
All-trans retinoic acid - prevents blast cells from proliferating at an immature age
+ Arsenic trioxide
Anthracycline for those at risk of relapse
Absolute neutrophil count
precise calculation of the number of circulating neutrophils
DROPS in AML
Consolidation therapy
Done to reduce the chances of recurrence of leukemia
usually contains cytarabine
HSCT
Hematopoietic stem cell transplantation
+ Aggressive chemo
+ Radiation therapy
Goal is to DESTROY patient hematopoietic function
PT is then “rescued” by the infusion of normal HSCT
Most common bleeds in AML
GI
Pulmonary
Vag
Intracranial
DIC is common, more so with APL
As tumors die uric aid and phosphorus will increase. Monitor
Kidneys
Chronic Myeloid leukemia CML 101
Pain in Liver Spleen and Long bones - excessive leukocyte proliferation
SOB, confusion - due to too much leukocytes
3 stages of CML
Chronic
Transformation
Acceleration (blast crisis)
Chronic - low complications
Transformation and acceleration - increase in complications
Rx treatment for CML
Tyrosine kinase inhibitors
Imatinib
HSCT if not Rx progress
Transformation phase CML S/S
bone pain, fever, weight loss
Spleen will enlarge
Anemia/Thrombocytopenia
Acceleration (blast crisis) phase CML S/S
Same as AML
Induction therapy
Nursing management of CML
PCR to detect levels of BCR-ABL molecules
Major molecular response Benchmark for determining efficacy
Biggest issue with taking tyrosine therapy is ADHERENCE, STRESS importance of taking meds
Acute lymphocyte leukemia ALL 101
uncontrolled proliferation of immature B lymphocytes and T lymphocytes
Common in kids and those over 50y
S/S of ALL acute lymphocyte leukemia
v in granulocytes erythrocytes and platelets
^ in IMMATURE leukocytes
Highest rate of organ infiltration (liver spleen bones)
Attacks CNS - Cranial nerve palsies and Headache/V
Treatment for ALL
Chemo
Cranial irradiation if CNS
Rx for ALL
Corticosteroids
Vinca alkaloids
Anthracyclines
HSCT in worst case
These meds are toxic to the LIVER
Due to corticosteroid use in ALL complications may include
Resp infection
Avascular necrosis
Chronic Lymphocyte Leukemia CLL
Most prevalent type of adult leukemia
Familial predisposition exists
Chronic Lymphocytic Leukemia CLL patho
B lymphocyte malignancy
Mature cells escape apoptosis
Excessive accumulation of cells in the marrow and circulation
How many stages of CLL
4
1st stage of CLL
increase in lymphocytes exceeding 100,000/mm
In CLL, malignant cells are so small that they don’t affect
Pulmonary or cerebral function
Mostly affects lymph nodes and spleen
Immunophenotyping of circulating B cells
Critical to establish diagnosis and gauge prognosis of CLL
CLL autoimmune complications
Anemia
Thrombocytopenia
S/S of CLL
^ lymphocytes
Enlargement of lymph nodes
Enlargement of spleen
CLL “B symptoms”
Fever
Drenching sweat (especially at night)
Unintentional weight loss
Watch for Infections
Calculate functional status
Life expectancy independent of CLL
Creatinine clearance
ADLs
The better you score the more aggressive therapy you can handle
Treatment for CLL
Immunotherapy and Chemo
If not effective, Kinase inhibitors
Side effect of Fludarabine used in CLL
Bone marrow suppression - neutropenia, thrombocytopenia etc.
Side effects of Alemtuzumab
Drop in B and T cells = high risk for infections
Basic Nursing focus with leukemia
Infection and bleeding
Mucositis management
Nutrition and Leukemia
Small frequent feedings
soft texture
moderate temperature
Daily body weight
Pain and leukemia
Tylenol
Sponging with cool water NO COLD
PCA (patient controlled analgesia)
Fatigue and leukemia
Stationary bike
Physicals therapy
Just sitting up during the day will improve tidal volume
F/E and leukemia
Measure I&Os - dehydration and fluid overload
CBC BMP - lytes, BUN, creatinine, hematocrit
K and Mag are frequent IVs
With leukemia don’t forget to manage
Hygiene
Anxiety and grief
Spiritual well-being
Lymphoma
Lymph node tumors
Can involve spleen, GI tract, liver, bone marrow
2 types, Hodgkin and non-Hodgkin
Hodgkin lymphoma 101
Rare, high cure rate
happens between 15y and 34y or over 60y
familial pattern
Hodgkin lymphoma patho
Single node origin
Reed-Sternberg Cell - huge immature lymphoid tumor cell, Core cell of the disease, all benign cells around it just support it.
S/S of hodgkin lymphoma
Enlargement of one or more lymph nodes on neck, Painless and firm
Cervical, Supraclavicular and mediastinal nodes most common
Mediastinal mass may be large enough to close trachea and cause dyspnea
Organ S/S of hodgin lymphoma
Organ compression
Pulmonary effusion
Jaundice
Abdominal pain
Bone pain
B symptoms
B symptoms
Fever
Drenching seats
Weight loss
Erythrocyte sedimentation rate
Rate of RBC settling - elevation indicates hodgkin lymphoma
Diagnosing hodgkin lymphoma

Staging
Assessing the extent of hogkins
like b symptoms
lymph node palpation
spleen and liver size
Xray and CT
PET positron emission tomography
Treatment for hodkins
Chemo plus meds
MoAb - attack’s Reed Sternberg but also attacks T and B cells
Hodgkins survivors are at risk of
Other cancers
Cardiovascular diseases
Endocrine system problems
Nursing management of hodkins
Check for secondary malignancy
Decrease tobacco, alcohol and exposure to carcinogens/excessive sunlight
non-hodgkin lymphoma NHL
neoplastic excess growth of lymphoid tissue
B and T lymphocyte overgrowth
As opposed to hodgkin, in NHL tissues are largely infiltrated
spread is unpredictable
NHL is the _ most common cancer
6th
S/S of NHL
Lymphadenopathy (swelling of lymph nodes) is most common
B symptoms
Masses can mess with organ function like breathing problems, renal problems, nausea
Indolent vs Aggressive NHL
Indolent -small cells distributed in circular pattern
Aggressive - large cells distributed in diffuse pattern
Staging for NHL
CT PET
Bone marrow biopsies
Cerebrospinal fluid analysis
Predictors for lymphomas

In Lymphoma has CNS symptoms treat with
Cranial radiation
Intrathecal chemo
Other therapies for lymphomas
Immunotherapy
Radiopharmaceutical agents
HSCT
Most common treatment for NHL
Chemo and radiation
Nursing management for NHL
Fatigue due to chemo and radiation
Risk of infection due to suppression of immunity
Teach pt about monitoring S/S of infection
Screen survivors regularly
NHL survivors are faced with handling
Fatigue, depression, anxiety, cardiac and pulmonary toxicity
Recommendations for cancer survivors
Good BMI
Smoking cessation

Mucositis
How to treat mucositis
Palifermin IV
Radiation therapy lead to skin
Integrity issues
Cancer and hair
Alopecia
begins 2 to 3 weeks after chemo and radiation starts
If a tumor metastasizes at the epithelium this lead to
Malignant skin lesions
Monitor lesions for size, appearance, pain, drainage and evidence of infection

approaches to treat symptoms
rehabilitative needs
late effect monitoring
surveillance and screening for new cancers
Pain management in pallative care
have analgesics on a schedule instead of PCA
